.My invention relates to machines formal;- ingand settingone-piece can liners in which the liner is automatically wound from a liner magazine upon a liner form over which and over the wound and folded liner thecan to be lined is telescoped and from which the can and liner are removed with the liner folded at its bottom and set within the can ready to receive the contents to be packed.

The main object of the invention is to provide automatic mechanism to make,fold and set the liners.

Other objects will appear.

Fig. 32 is a section showing an alternate arrangement for operating the folders which dispenses with the folder-lever and is pref erable in a large machine where space for the cams required can be obtained. Fig. 33 is a section of the bellows cam track indicated inFigure 3 by the line 33-33. I

A suitable frame is constructed to include three plates 15, 16 and 18 and seven revoluble discs 19, 20, 22, 23, 25, 26 and 28.

The discs aforesaid are secured to a main shaft which is driven by any suitable mechanism and is revoluble in bearings supported by the plates as shown.

The liners 6 preferably consist of rectangular sheets of parchment paper out to a length equal to the circumference of the can plus allowance for the side lap and to width equal to the height of the can plus allowance for the lap on the top and bottom of the can.

The liner magazine is secured to the frame aforesaid at 29, figures 2, 4, 12 and 13, in which a follower 31 is drawn back against the compression spring 32, bearing against a fixed plate 31, to insert the liners. \Vhen the follower is released, the liners are pressed against the corner clips 33, which should be very thin or needle-like, and the center clip 34, Figures 12, 13 and 14. The curvature of the follower 31 is adapted to hold the outside liner or that one positioned for action in an are adjacent to the path of the rotary liner form 36.

The present form of the invention is arranged in six units, all alike, each having a liner form 36.

One of these units and its cycle of operations will be described.

The unit approaches the liner magazine 29, say at A.

Above the can-holders 35 and concentric therewith is a liner form 36 mounted on the hollow form shaft 37 (Fig. 5) and connected with bellows 38, the bottom of the latter being secured to the disc at 39.

The path of the liner form 36 is adjacent to the exposed liner in the magazine, or that liner ready for action, and the liner form is positioned vertically by the magazine 29 to allow for the top and bottom laps.

Advancing from A, the air holes 40, Figure 5, are presented to the exposed liner with a margin of about one inch.

Here, at B, the bellows cam track 41, Figures 1 and 3, is elevated and the bellows cam spring 42 forces the bellows cam follower 43 to open the bellows 38 and air is thereby drawn into the bellows through the air chamber 44, Figure 5, at the holes 40 under the suction valve 45 and the margin of the liner is pulled from the magazine and held to the liner form 36 over the air holes 40.

Form gear 46 is secured to the form shaft 37 and mates with and successively engages the sections of gears secured to the gear band 47 and adjustably spaced apart at 48, 49, 50 and 51.

From B, the liner form revolves and the liner is wound on the liner form.

A stulfing box 52 facilitates revolution of the form shaft 37 without breaking the suction.

The diameter of the pitch circle of the form-gear 46 should equal the diameter of the form to harmonize the winding of the liner on the liner form with unwinding from the magazine. Otherwise the liner will rumple.

The can holder 35 is formed to provide a cam 53, Figures 4, 12, 13 and 14, which engages its mate 54 in passing along the path indicated by the dotted line in Fig. 1.4, Figures 13 and 14, to depress the magazine center clip 34 and allow the unwindlng of the liner from the magazine while the form is passing the clip, after which the latter springs up and returns to its normal position and holds the next liner in place. It will be understood that the cam 53, traveling with its can holder, extends far enough out at a proper level to depress the cam 54 and attached spring arm and clip 34 and release the can-liner which is being rolled up on the former, which is in axial line with and above said can holder.

The form gear 46 has twelve teeth and the first gear section 48 has twenty-one teeth, the first three of which are provided to turn the air holes 40 fairly to the margin of the liner as described, and the next twelve to turn the liner form one complete revolution during which the liner is held to the liner form entirely by suction. At this point the cam 56 (Fig. 5) declines and the roller 57 together with the hood rod 58 and sliding hood 59 are let down so the liner is held on the form by the hood clip 60 (Fig. 7 The remaining six teeth in the gear section 48 turn the liner form 36 half revolution so that the air holes 40 and the lap 61 of the liner face the folder head 62 positioned for the first step in folding the liner as shown in Figures 15, 16, 17, 18 and 19.

The folder head 62 is supported by the" moved inwardly at 66 (Fig. 2) and the folder bar 63 is moved outward by means of the folder cam lever 67 pivot-ally secured to the disc at 68.

Thus while advancing from C to D the folder head 62 performs the first step in folding the liner as shown in Figures 20, 21 and 22.

From D to E the form gear 46 provided with twelve teeth engages the second gear section 49 with six teeth and the liner form 36 makes half turn while the folder head 62 remains inactive.

The pilot head 69 mates with notches T0 in the pilot flange, Figures 1, 5 and 8, and insures accurate positioning of the liner form 36 for action of the folder head 62.

From E to F, the folder head 62 co-operating with the folder cam follower 65 and the folder cam lever 67, makes the second step in folding-the liner as shownin Figures 23, 24 and 25. 1

From F to G, the liner form 36, co-operating with the other parts as described, makes a quarter-turn.

From G to H, the folder head-62 makes the third step in folding the lineras shown in Figures 26, 2'? and 28. i

From H to I, the form gear 46 engages six teeth of the gear section 51 and the liner form 36 makes a half turn. 7

From I to J, the folder head 62, co-operating with the other parts as described, makes the fourth and the last step in fold ing the liner as shown in Figures 29, 30 and 31.

By changing the engagement of the notches with the head 69, the inward movement of the cam roller 65 may beincreased toincrease the outward movement of the folder'head 62 to press down and smooth the folds 71 and 72 with the flat part of the surface of the folder head as shown, Figure 31. i Y

. At K, Figure 4, the can to be lined is re-* ceived by the can holder 35'. The dotted lines show the position of disc 4 above the section plane, Figure. 4. p

73 is a moving belt, 74 shows the rail of the can race and 75 is a spring over which the can holder 35 passes and by which the next can is positioned to be received by the can holder of the next unit.

At L, the can-lift cam 76 begins to lift the can-lift roller 77 compressing the canlift spring 78 and raising the can-lift 79 through the can-lift slot 80, Figure 4, and impales the can on the liner form 36.-

At M, Figure 3, the bellows cam 41 depresses the bellows roller 43 producing an air blast from the bellows through the form shaft 37, Figures 1, 5 and '10, to, the liner form 36 and through the blast valve 81 (Figs. 5' and 10) into the can expanding the liner to full contact with the. sides and edges of the can. I v 4 At N, the can-lift cam 76 declines and let-s down the can-lift 7 9. Co-incidently the continued depression of the bellows 38 and the consequent air blast aforesaidforces off the can with the liner set and expanded around within the sides and bottom edges of the can. v V

At 0, the lined can is released on the discharge disc 82 and the cycle is repeated.

After the can has been filled, any suitable machine can be used to close the liners over the food to be canned, or the f-oldingmay be performed by hand.
